Unix Databases

The main databases available on our system are mSQL and mySQL . They can be accessed via PHP (probably the most widely used method).

Note: midairdesign offers mSQLand mySQL databases as a free service to our premium customers. We do not provide tech support for databases; however, we have excellent tutorials on our site regarding mSQL and PHP.

"mSQL is a lightweight database engine designed to provide fast access to stored data with
low memory requirements." - mSQL Manual

Note: The only types of database that midairdesign permits on our system are mSQL and mySQL; other database types make heavy use of system resources. Allowing them would negatively impact the performance of other clients' websites.

First, some basics:

For example, if your domain name is xyz.com, the name of your database will be:

xyz

Want to do a quick and easy backup of your database? Use msqldump! Just follow these steps:

  1. Run the command msqldump databasename > filename.dump. This creates a flat ascii file with all of the commands necessary to totally recreate your mSQL database. (If you just run msqldump databasename without directing it to a file, then it echoes to the screen! Yuck, yuck, phooey, phooey!)

  2. You can use this for a daily backup, delete or manipulate your tables, whatever. As long as you have this ascii file, you're OK.

  3. If you are experiencing problems with a table (key fields not working properly, spaces inserted into integers, etc.), then you can run an msqldump, delete the current structure, and feed the data back in with the command
    msql databasename < filename.dump. All better now!
